ABSTRACT

Objective@#The aim of this study was to compare the survival rates of Korean females aged 40 to 49 years with breast cancer detected by supplemental screening ultrasound (US) or screening mammography alone. @*Materials and Methods@#This single-institution retrospective study included 240 patients with breast cancer (mean age, 45.1 ± 2.8 years) detected by US or mammography who had undergone breast surgery between 2003 and 2008. Medical records were reviewed for clinicopathologic characteristics and detection methods. Disease-free survival (DFS) and overall survival (OS) were compared between patients with breast cancer in the US and mammography groups using the log-rank test. Multivariable cox regression analysis was used to identify independent variables associated with DFS and OS. @*Results@#Among the 240 cases of breast cancer, 43 were detected by supplemental screening US and 197 by screening mammography (mean follow-up: 7.4 years, 93.3% with dense breasts). There were 19 recurrences and 16 deaths, all occurring in the mammography group. While the US group did not differ from the mammography group in tumor stage, the patients in this group were more likely to undergo breast-conserving surgery and radiation therapy than the mammography group.The US group also showed better DFS (p = 0.016); however, OS did not differ between the two groups (p = 0.058). In the multivariable analysis, the US group showed a lower risk of recurrence (hazard ratio, 0.097; 95% confidence interval, 0.001–0.705) compared to the mammography group. @*Conclusion@#Our study found that Korean females aged 40–49 years with US-detected breast cancer showed better DFS than those with mammography-detected breast cancer. However, there were no statistically significant differences in OS.

ABSTRACT

PURPOSE: The 8th edition of the American Joint Committee on Cancer (AJCC) staging manual introduced a new prognostic staging system for breast cancer. This study aimed to evaluate the changes in staging distribution and predictive power of the new staging system.METHODS: Of the 12,275 patients with breast cancer identified from the Severance Breast Cancer Registry who underwent surgery between 1978 and 2016, 12,125 patients met the inclusion criteria.RESULTS: In both the 7th and 8th staging systems, stage I patients constituted the largest proportion (38.2% and 48.4%). Migration from the 7th to 8th edition of the AJCC manual resulted in a decrease in stage II population and an increase in stage I and III populations. A total of 1,293 (15.4%) patients were upstaged, and 1,201 (14.3%) were downstaged. Downstaged patients had better recurrence-free and overall survival (p < 0.001). Pathologic complete response after neoadjuvant therapy showed good prognosis as p stage 0, and yp stages I and III showed poorer outcomes than the same p stage (p < 0.001).CONCLUSIONS: Staging migrations are common in early breast cancer under the prognostic staging system. The prognostic staging system of the 8th edition of the AJCC manual discriminates survival outcomes better than the anatomical staging system of the 7th edition of the AJCC manual.

ABSTRACT

PURPOSE: Dose-dense chemotherapy (DD-CT) is a preferred (neo)adjuvant regimen in early breast cancer (BC). Although the results of reported randomized trials are conflicting, a recent meta-analysis showed improved overall and disease-free survival with DD-CT compared to conventional schedules. However, no DD-CT safety data for Korean BC patients are available. This phase II study was conducted to evaluate the safety and efficacy of pegteograstim in Korean BC patients receiving DD-CT. MATERIALS AND METHODS: Patients with operable (stage I-III), histologically confirmed BC received four cycles of intravenous doxorubicin (60 mg/m2) and cyclophosphamide (600 mg/m2) on day 1 every 2 weeks as neoadjuvant or adjuvant therapy. Pegteograstim (6.0 mg) was administered subcutaneously on day 2 of each cycle. The primary endpoint was the incidence of febrile neutropenia (FN). The secondary endpoints were safety and tolerability. RESULTS: Of 63 patients, one (1.6%) developed FN during all cycles of DD-CT. Dose delay was observed in four patients (6.3%) and dose reduction in two (3.2%) during DD-CT. Frequent adverse events (AEs) were nausea, alopecia, generalized muscle weakness, myalgia, mucositis, anorexia, dyspepsia, and diarrhea; most AEs were related to chemotherapy. Grade 3-4 AEs were reported in five of 63 patients (7.9%), and all grade 3 and 4 AEs were related to chemotherapy. Adverse drug reactions possibly linked to pegteograstim were abdominal pain, bone pain, myalgia, generalized muscle weakness, and headache in five of 63 patients (7.9%). CONCLUSION: Dose-dense AC (doxorubicin/cyclophosphamide) chemotherapywith pegteograstim support is a tolerable and safe regimen in Korean early BC patients.

ABSTRACT

PURPOSE: Sentinel lymph node (SLN) biopsy (SLNB) is widely performed for axillary staging in patients with breast cancer. Based on the results of frozen section examination (FSE), surgeons can decide to continue further axillary dissections. This study aimed to verify the accuracy of FSE for SLNs. METHODS: We reviewed the records of 4,219 patients who underwent SLNB for primary invasive breast cancer between 2007 and 2016 at the Severance Hospital. We evaluated factors associated with the false-negative results of FSE for SLNs using the Generalized Estimating Equations model. RESULTS: A total of 1,397 SLNs from 908 patients were confirmed to be metastatic. Seventy-one patients (1.7%) had confirmed pathologic N2 or N3 stage. Among metastatic SLNs, micrometastasis was found in 234 (16.8%). The overall accuracy of SLNB was 98.5%. The sensitivity and false-negative rate of FSE were 86.4% and 13.6%, respectively. Several clinicopathological factors, including the size of SLN metastases, suspicious preoperative axillary lymph nodes, and luminal B subtype, were associated with a higher rate of false-negative results. CONCLUSION: Most patients were not indicated for axillary lymph node dissection. Some patients may show transition in their permanent pathology due to the size of the metastatic node. However, the false-negative results of FSE for SLNs based on the size of the metastatic node did not change our practice. Therefore, intraoperative FSE for SLN should not be routinely performed for all breast cancer patients.

ABSTRACT

PURPOSE: To validate and update a nomogram for predicting ductal carcinoma in situ (DCIS) upstaging in preoperative biopsy. MATERIALS AND METHODS: Medical records of 444 preoperative DCIS patients were evaluated and used to validate a previous version of the Severance nomogram for predicting DCIS upstaging in preoperative biopsy. Patients were divided into two groups according to the final postoperative pathology. Univariate and multivariate analyses with the chi-square test, Student's t-test, and binary logistic regression method identified new significant variables. The updated nomogram was evaluated with the C-index and Hosmer—Lemeshow goodness of fit test. RESULTS: The area under a receiver operating characteristic curve for comparison with the previous nomogram was 0.48. In postoperative pathology, the pure DCIS and invasive cancer groups comprised 345 and 99 cases, respectively. Approximately 22.3% of patients preoperatively diagnosed with DCIS were upstaged to invasive cancer. Significant variables in the univariate analysis were operation type, human epidermal growth factor receptor 2 overexpression, comedo necrosis, sonographic mass, mammographic mass, preoperative biopsy method, and suspicious microinvasion in preoperative biopsy. In multivariate analysis, operation type, sonographic mass, mammographic mass, and suspicious microinvasion were risk factors for upstaging. The updated model with these variables showed moderate discrimination and was appropriate in the calibration test. CONCLUSION: The previous nomogram did not effectively discriminate upstaging of preoperative DCIS in an independent cohort. An updated version of the nomogram appears to provide more accurate information for predicting preoperative DCIS upstaging.

ABSTRACT

PURPOSE: IBTR! 2.0 nomogram is web-based nomogram that predicts ipsilateral breast tumor recurrence (IBTR). We aimed to validate the IBTR! 2.0 using an external data set. MATERIALS AND METHODS: The cohort consisted of 2,206 patients, who received breast conserving surgery and radiation therapy from 1992 to 2012 at our institution, where wide surgical excision is been routinely performed. Discrimination and calibration were used for assessing model performance. Patients with predicted 10-year IBTR risk based on an IBTR! 2.0 nomogram score of 10% were assigned to groups 1, 2, 3, and 4, respectively. We also plotted calibration values to observe the actual IBTR rate against the nomogram-derived 10-year IBTR probabilities. RESULTS: The median follow-up period was 73 months (range, 6 to 277 months). The area under the receiver operating characteristic curve was 0.607, showing poor accordance between the estimated and observed recurrence rate. Calibration plot confirmed that the IBTR! 2.0 nomogram predicted the 10-year IBTR risk higher than the observed IBTR rates in all groups. High discrepancies between nomogram IBTR predictions and observed IBTR rates were observed in overall risk groups. Compared with the original development dataset, our patients had fewer high grade tumors, less margin positivity, and less lymphovascular invasion, and more use of modern systemic therapies. CONCLUSIONS: IBTR! 2.0 nomogram seems to have the moderate discriminative ability with a tendency to over-estimating risk rate. Continued efforts are needed to ensure external applicability of published nomograms by validating the program using an external patient population.

ABSTRACT

PURPOSE: Sentinel lymph node biopsy (SLNB) can be performed when node-positive disease is converted to node-negative status after neoadjuvant chemotherapy (NCT). Tattooing nodes might improve accuracy but supportive data are limited. This study aimed to investigate the feasibility of charcoal tattooing metastatic axillary lymph node (ALN) at presentation followed by SLNB after NCT in breast cancers. MATERIALS AND METHODS: Twenty patientswith cytology-proven node metastases prospectively underwent charcoal tattooing at diagnosis. SLNB using dual tracers and axillary surgery after NCT were then performed. The detection rate of tattooed node and diagnostic performance of SLNB were analyzed. RESULTS: All patients underwent charcoal tattooingwithout significant morbidity. Sentinel and tattooed nodes could be detected during surgery after NCT. Nodal pathologic complete response was achieved in 10 patients. Overall sensitivity, false-negative rate (FNR), negative predictive value, and accuracy of hot/blue SLNB were 80.0%, 20.0%, 83.3%, and 90.0%, respectively. Retrieving more nodes and favorable nodal response were associated with improved performance. The best accuracy was observed when excised tattooed node was calculated together (FNR, 0.0%). Cold/non-blue tattooed nodes of five patients were removed during non-sentinel axillary surgery but clinicopathological parameters did not differ compared to patients with hot/blue tattooed node detected during SLNB, suggesting the importance of the tattooing procedure itself to improve performance. CONCLUSION: Charcoal tattooing of cytology-confirmed metastatic ALN at presentation is technically feasible and does not limit SLNB after NCT. The tattooing procedure without additional preoperative localization is advantageous for improving the diagnostic performance of SLNB in this setting.

ABSTRACT

PURPOSE: We investigated the changes in serum 25-hydroxyvitamin D (25[OH]D) levels before and after neoadjuvant chemotherapy (NCT) and the associations with pathologic complete response (pCR) and survival in patients with breast cancer. METHODS: Serum 25(OH)D concentrations were measured pre- and post-NCT in 374 patients between 2010 and 2013. Based on a cutoff of 20 ng/mL, patients were categorized into “either sufficient” or “both deficient” groups. The associations with clinicopathological data, including pCR and survival, were analyzed using multivariable analyses. RESULTS: Patients with either pre- or post-NCT sufficient 25(OH)D levels accounted for 23.8%, and the overall pCR rate was 25.9%. Most patients showed 25(OH)D deficiency at diagnosis and 65.8% showed decreased serum levels after NCT. Changes in 25(OH)D status were associated with postmenopause status, rural residence, baseline summer examination, and molecular phenotype, but not pCR. No association between survival and 25(OH)D status was found, including in the subgroup analyses based on molecular phenotypes. CONCLUSION: Most Korean patients with breast cancer showed vitamin D deficiency at diagnosis and a significant decrease in the serum concentration after NCT. No association with oncologic outcomes was found. Therefore, although optimal management for vitamin D deficiency is urgent for skeletal health, further research is warranted to clearly determine the prognostic role of vitamin D in patients with breast cancer who are candidates for NCT.

ABSTRACT

PURPOSE: There are few reports from Asian countries about the long-term results of aromatase inhibitor adjuvant treatment for breast cancer. This observational study aimed to evaluate the long-term effects of letrozole in postmenopausal Korean women with operable breast cancer. METHODS: Self-reported quality of life (QoL) scores were serially assessed for 3 years during adjuvant letrozole treatment using the Korean version of the Functional Assessment of Cancer Therapy-Breast questionnaires (version 3). Changes in bone mineral density (BMD) and serum cholesterol levels were also examined. RESULTS: All 897 patients received the documented informed consent form and completed a baseline questionnaire before treatment. Adjuvant chemotherapy was administered to 684 (76.3%) subjects, and 410 (45.7%) and 396 (44.1%) patients had stage I and II breast cancer, respectively. Each patient completed questionnaires at 3, 6, 12, 18, 24, 30, and 36 months after enrollment. Of 897 patients, 749 (83.5%) completed the study. The dropout rate was 16.5%. The serial trial outcome index, the sum of the physical and functional well-being subscales, increased gradually and significantly from baseline during letrozole treatment (p<0.001). The mean serum cholesterol level increased significantly from 199 to 205 after 36 months (p=0.042). The mean BMD significantly decreased from −0.39 at baseline to −0.87 after 36 months (p<0.001). CONCLUSION: QoL gradually improved during letrozole treatment. BMD and serum cholesterol level changes were similar to those in Western countries, indicating that adjuvant letrozole treatment is well tolerated in Korean women, with minimal ethnic variation.

ABSTRACT

Robotic surgical systems enhance surgical accuracy and efficiency by applying advanced technologies such as artificial arm joints to provide higher degrees of freedom of movement and high-quality three-dimensional images. However, the application of robotic surgical systems to breast surgery has not been widely attempted. The robotic system would improve cosmesis by enabling surgery using a single small incision. We report the first case of a gasless robot-assisted nipple-sparing mastectomy and immediate reconstruction in a patient with early breast cancer.

ABSTRACT

PURPOSE: Clinicopathologic characteristics of patients with both thyroid and breast cancer during their lifetime were analyzed to investigate the association between the two malignancies according to the order of incidence.METHODS: A total of 405 patients who underwent surgery for breast and thyroid cancer at Severance Hospital between 1995 and 2014 were retrospectively selected and classified into 3 groups according to the order of incidence of the two cancers: simultaneous cancer (S), thyroid cancer followed by breast cancer (TB), and breast cancer followed by thyroid cancer (BT). Univariate analysis was conducted to compare parameters.RESULTS: S, TB, and BT groups were 166 (41.0%), 96 (23.7%), and 143 (35.3%) patients, respectively. In TB and BT groups, tumor size and surgical site for secondary cancer were smaller; therefore, adjuvant treatments were less frequently required for secondary cancer. ER positive rate was 77.1% in S, 75% in TB, and 63.7% in BT groups (P=0.027). The ratio of ER negative was higher in the group with BRAF mutation. Survival rate for index tumor was higher in order from TB, and BT, followed by S groups without statistical difference.CONCLUSION: It is difficult to find a significant difference according to the order of occurrence except by screening test, and more studies are needed in the future. Establishing an appropriate screening program is important in order to detect secondary breast or thyroid cancer after surgery for thyroid or breast cancer.

ABSTRACT

PURPOSE: Breast-conserving surgery (BCS) shows no difference in survival rates compared with total mastectomy. So, BCS is considered standard breast surgery with modified radical mastectomy. But in patients who received BCS, there is a risk of local recurrence in their long term follow up periods. Especially, BCS of young age is controversial regarding oncologic safety because of local recurrence. In this study, we struggle to confirm the oncologic safety of BCS compared with total mastectomy under the age of 35 in South Korea.METHODS: All patients who underwent surgery for breast cancer were 5,366 at Severance Hospital, Yonsei University Health System, from January 1981 to April 2008. Of them, patients younger than 35 years old were 547. We excluded patients who received chemotherapy before surgery and included only stage 1 and 2 patients who identified through the pathology after surgery. Finally, we got 367 patients; total mastectomy was performed in 245 and BCS, in 122. We compared clinicopathological characteristics and oncologic outcomes between two groups using SPSS program.RESULTS: In patients received BCS, a local recurrence rate was 7.7% at 5 years and up to 20.3% at 10 years. In patients received total mastectomy, a local recurrence rate was 1.9% over 10 years (P<0.001). However, there was no difference in 5-year and 10-year overall survival rates between two groups (P=0.689). Adjuvant chemotherapy decreased local recurrence rate in BCS patients (P=0.019).CONCLUSION: So, we concluded that BCS under the age of 35 has oncologic safety with undergoing chemotherapy.

ABSTRACT

Male breast cancer is a rare disease, accounting for about 1% of all breast cancers. Little is known about the etiology of male breast cancer, especially developed in young man. Genetic and hormonal factors have been reported to be involved in its pathogenesis. But, less is known regarding the role of anthropometric or other endocrine risk factors. It's extremely rare for breast cancer to occur in young male patient because male breast cancer generally occur in old patients. A 29-year-old male was diagnosed with breast cancer in our institution who was with diabetes and obesity. There was no specific risk of genetic or hormonal factors for his breast cancer.

ABSTRACT

PURPOSE: Ultrasound-guided fine needle aspiration (US-FNA) in thyroid nodules is presently most commonly used to identify whether these nodules are benign or malignant. However, atypical or follicular lesions of undetermined significance (AUS/FLUS), as categorized in the Bethesda System for reporting the results of FNA, cannot be classified as benign or malignant. Therefore, several clinical factors should be considered to assess the risk of malignancy in patients with AUS/FLUS. The purpose of the present study was to determine which clinical factor increased the risk of malignancy in patients with AUS/FLUS. METHODS: A retrospective study was done on 129 patients with fine needle aspiration categorized as AUS/FLUS from January 2011 through April 2015. Univariate and multivariate analyses were performed to assess the independent effect of risk factors such as age, sex, size of nodule, atypical descriptors, and ultrasonography criteria for malignancy. RESULTS: We identified that the presence of spiculated margin (odds ratio [OR], 5.655; 95% confidence interval [CI], 2.114-15.131; P = 0.001), nuclear grooving (OR, 3.697; 95% CI, 1.409-9.701; P = 0.008), irregular nuclei (OR, 3.903; 95% CI, 1.442-10.560; P = 0.001) were shown to be significantly related to malignancy on univariate and multivariate analyses. CONCLUSION: We recommend that surgical resection of thyroid nodules be considered in patients with AUS/FLUS showing the histologic findings such as nuclear grooving, irregular nuclei along with spiculated margin of ultrasonographic finding.

ABSTRACT

Since recurrent bilateral breast infection due to nontuberculous mycobacterium (NTM) is rare, its diagnosis is easily overlooked; in addition, complete recovery is often difficult to achieve. We report a case of recurrent bilateral infection in a 35-year-old woman who had completed treatment for NTM. Although various infectious diseases show similar clinical conditions and imaging findings, recurrences should raise suspicion of NTM infection, and this possibility should be considered in differential diagnoses.

ABSTRACT

PURPOSE: Weight gain after diagnosis of breast cancer is a profound issue that may negatively impact cancer prognosis. However, most existing research on weight change has been conducted in Western countries. In addition, several factors related to weight gain have been reported; however, the evidence is inconsistent. The purpose of this study was to examine weight gain and its correlates among Korean breast cancer survivors. METHODS: A total of 132 female breast cancer survivors were recruited from one university hospital in South Korea. Participants completed anthropometric measurements (i.e., body weight, height) and a self-reported questionnaire, including the International Physical Activity Questionnaire Short Form and Mini Dietary Assessment. RESULTS: The mean weight change was -0.09 kg (SD = 4.28). Only 27 women (19.7%) gained more than 5% of their weight at diagnosis, 59.1% maintained weight, and 21.2% lost weight. In multivariate logistic regression analysis, significant correlates of weight gain were younger age, obesity at diagnosis, duration of more than 36 months since diagnosis, and low diet quality. CONCLUSION: Younger women, women who were obese at diagnosis, women with more than 36 months since diagnosis, or women who showed lower diet quality should be considered at high-risk for weight gain. Findings from our study suggest that optimal weight management strategies should be developed using ethnically- or culturally-appropriate approaches.

ABSTRACT

PURPOSE: Endovascular treatment for peripheral arterial obstructive disease (PAOD) is replacing traditional arterial bypass in the western world. Yet there are few reports to evaluate the pattern of clinical practice pattern for PAOD in Korea. This study was conducted to evaluate the treatment pattern for PAOD between endovascular treatment and arterial bypass, and to compare their clinical characteristics. METHODS: We conducted a retrospective study on the prospectively maintained database of patients who underwent endovascular treatment and arterial bypass for PAOD from March 2005 to December 2009 in Inha University Hospital. The aortoiliac lesions and femoropopliteal lesions were categorized by the Trans Atlantic Inter-Society Consensus (TASC) II classifications. Their treatments and clinical characteristics were compared between the former period (2005~2007 y) and the latter period (2008~2009 y). RESULTS: Three hundred nine cases (178 patients) were treated for PAOD by either arterial bypass or endovascular treatment. The patients' mean age was 69.1+/-11.3 year old. There was no difference in clinical characteristics between the two periods except for age. Endovascular treatments of both aortoiliac and femoropopliteal arterial lesions were increased in the latter period (P=0.023, P<0.001). Also, the endovascular treatments were increased in the TASC C and D aortoiliac and femoropopliteal lesions in the latter period (P=0.020, P<0.001). CONCLUSION: Endovascular treatment for PAOD is increasing in clinical practice and this shows feasibility in critically ill patient with TASC C and D lesions, although arterial bypass is still important.

ABSTRACT

BACKGROUND/AIMS: Surgery has been the mainstay of treatment for duodenal perforations after the introduction of endoscopic retrograde cholangiopancreatography (ERCP). Yet there have recently been arguments that conservative management with or without endoscopic intervention may be possible and safe. METHODS: For the patients who received ERCP at Inha University Hospital from Jan. 2001 to Dec. 2007, we retrospectively analyzed the clinical manifestations, the treatment and the clinical outcomes of the cases with duodenal perforation. RESULTS: Among the 1708 ERCP cases, duodenal perforation occurred in eleven (0.6%) patients. There were two cases of duodenal perforations (type I), four cases of peri-Vaterian injury (type II), two cases of bile duct perforations (type III) and three cases of retroperitoneal perforations (type IV). Six patients (55%) were treated surgically while the others were managed conservatively. Except for one death (9.1%), ten patients fully recovered. Either residual diseases or fluid collections, as seen on CT, were present in the surgically managed patients. The median time interval between ERCP and surgery was 19 hours (range: 8~30 hours). CONCLUSIONS: To decide on the management of duodenal perforation after ERCP, the presence of residual disease or the leakage of intraluminal contents should be considered along with the type of the perforation.

ABSTRACT

PURPOSE: Diabetes mellitus refers to one of several risk factors for cardiovascular diseases, renal failure and so on. Medical treatments of T2DM cannot suggest a perfect cure. But gastric bypass resulting in the exclusion of the duodenum and proximal jejunum has been shown to improve or resolve T2DM. The goal of this study is to evaluate the effect of duodenojejunal bypass for T2DM patients below BMI 25 kg/m2 in early postoperative period. METHODS: Duodenojejunal bypass was performed on 25 patients at Inha University Hospital from July 2009 to April 2010. We compared 75 g OGTT, insulin, C peptide to those 7 days postoperative. The definitions for improvement are serum glucose level below 200 mg/dl of 75 g OGTT at 120 min or below 200 mg/dl at every other time in spite of over 200 mg/dl at 120 min. RESULTS: A total of 25 patients (15 men and 10 women) were included. Median value BMI was 23.17 kg/m2 and the mean duration of T2DM was 8.3 years. There was a significant decrease of postoperative 75 g OGTT levels from 176, 268, 345, 373, 371 mg/dl to 125, 170, 200, 225 and 241 mg/dl, respectively (P<0.001). Only patients' age was an independent factor resolution of T2DM based on this study. CONCLUSION: Duodenojejunal bypass could be one viable treatment modality for improving or resolving of T2DM although these are early results. This study has preliminary meanings only and the results of longer follow-up and a larger number of patients are necessary, by which we should be able to determine the effect and indications for surgical treatment of T2DM.
